Definitions
- the fuel mixes with the inflowing compressed air in such a way that a premixing/pre-evaporation process takes place in the tubular element 2.
- This process is intensified by the use of a Borda mouthpiece 34 at the air inlet of the tubular element 2 because of the turbulence thus arising.
- the fuel injection or blowing in of the fuel through the fuel nozzles 15' and 15" respectively must take place at a optimum distance from the Borda mouthpiece 34 but still within the region of the turbulence arising.
- the invention is therefore based on a mixed method of running with diffusion and premixed combustion in the load range.
- the proportional oil quantity ratio is then so chosen in each case that a method of running is possible with a sufficiently large margin from the resulting stability boundary S DM .
- the result of tests is that this is best attained if 90 to 95% of the fuel is fired according to the premixed principle and 5 to 10% of the fuel according to the diffusion principle.
- a mixed method of running with 10% diffusion proportion is shown in the diagram. From idling up to 15% load, running is carried out with one quarter of the available element, i.e. with only the group u in pure diffusion operation. With the increase in the fuel oil supply, ⁇ has become so small at 15% load that the group of elements v must be switched on again. At 20% load, the premixing system is then put into operation for all the elements of each of the groups u and v, which leads to a distribution of the fuel oil in the ratio quoted above. The reduction of the fuel at the diffusion nozzles at a constant air quantity produces a sharp rise in the excess air coefficient, as is shown by the interrupted line.
